CONTROLLING DEVICE roe ELECTRIC mas.

Application filed March 27, 1922. SeriaLNo. 547,315.

To all whom it may concern.

Be it known that I, CARL A. FAIRBANKS, a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented new. and useful Improvements in Controlling Devices for Electric Signs, of which. the following is a specification. I i

This invention relates to a controlling device for an electric sign of the type illustrated and described in the United States Patent Number l,3l3,141,granted June 8, 1920. The sign therein disclosed includes the representation of a portion ofthe human body and especially of the spinal column and some of the nerves directly associated therewith, and the mechanical structure includes means for imparting movement at intervals.

'ity of cams rigid therewith,a rocking arm for operation by each cam, and means actuated by said arm for actuating an element indicating displacement of a particular ver- 'tebra of the spinal column.

In the drawings, Figure 1 is a face view of the device, showing particularly the chart referred to below; Figure 2 is a view, in elevation, of a portion of the operating mechmainder of the operating mechanism, including the motor, cam shaft and rock shaft; Figure l is an elevation of the make and break mechanism, mounted on the cam shaft; Figure 5 is a Vertical transverse section through the gear casing, at the right of the fan of Figure 3; Figure 6 shows the mounting of the movable-vertebra 34; Figure 7 is a detail view of one of'the cams and rocking arms, for actuating a connecting rod by means of which shaft 32 is rocked, for moving the vertebra.

Proceeding to the description of the mechanism for actuating a cam shaft and suitable Manta;

makeland break devices,'the reference hum-,

ber 10 indicates a motor which includes armature shaft 11 carrying a fan 12, ai1d projecting into the gear casing 13 mounted on the base 14 a a worm 15 meshing with a worm wheel 16 on the shaft 1'5, and the-shaftlast named" The shaft is providedwith carries a worm 18 meshing with worin wheel 19 onthe cam shaft 20,

n the present instance four. cams are showmthese elements being designated21,

armsbeing illustrated as of channel shape, thec'am devices operating withinthelchannels. I

'Connected with each rocking arm is a wire or connecting rod such as'80, this element being pivoted, or loosely connected with arm of rock shaft 32 mounted in bearings 33. 811 the opposite ends'ofeach rock shaft is an element 34 representing a vertebra. 4

@penin'gs35 are provided in the chart 36 and the particular vertebrae 34 to be moved,

and 24m Pivotally mounted on shaft 25 are rocking arms 26, 27,28 and 29, these for indicating abnormal conditions, are visible through the openings, the remainingvertebrae'bemg illustrated on the chart.

In connection with the foregoing arrangement and construction, electric lamps are positioned in such manner as to best attract a attention'to the. condition which the device is intended to emphasize. As a certain lighting arrangement has been .fully *de scribed in connection with'thej patent before 1 mentioned, the circuits to be employed in connection with the present sign need not be described 1n detail, but as the make and break mechanism is operated directly from the cam shaft, it is proper to state that the,

contact disks 41 and 42 carried by and driven by cam shaft 20, carry metallic segments, through whichthe circuits are completed, several pairsof brushes 44 being mountedas shown on the insulating plates 47 andtS. a wire terminal 50, and a common lead or return is designated 51. 1 t Having thus described my invention, I claim: 7 a 1 In device of the class described, a cam shaft, a cam rigidthereon, an element representing a portion of the human anatomy subject to displacement, a chart with Associated with each brush is V which said element'is associated, means-for mounting said element to permit of move- 7 ment for attracting attention, the chart having a cut away portion through which the element specified is visible, and means for actuating said element from the cam,

2. Ina device of the class described, a cam shaft, a cam rigid thereon, a second'shaft, a rocking arm pivoted thereon and actuated by the cam, an element representing aportion of the human anatomy and mounted for movement to indicate an abnormal condition, a rock shaft for mounting .said element, and means for actuating the rock shaft from the rocking arm. i i

I 3. in a device of the class described, a cam shaft,a cam rigid thereon, a second shaft, a rocking arm pivoted thereon and actuated by thecam, an element representing a portion of the human anatomy and mounted for movement to indicate displacement, a rock shaft for mounting said element,'and

means for actuating the rock shaft from the rocking arm, said means last named including an arm on the rock shaft, and a connecting rod.

4:. In a device of the class described, a cam shaft, a cam rigid thereon, a second shaft,

a channeledjrocking arm pivoted thereon, the cam operating in the channeled portion for moving the arm about its pivotal mountr electric motorincluding'a shaft, avvormcarried by the shaft, a Worm Wheel meshing with the Worm, a camshaft, Worm gearing driven bythe aforesaid Worm and Worm gearwheel, a cam rigid'on the cam shaft, an additional shaft, a rocking arm pivoted thereon and positioned to be moved by the cam, intermittently, a display element to'be given a vibratory mo ven'ient, and means for imparting such movement upon the rocking of the aforesaid arm.

In testimony whereof I afliX-my signature.
